when a 'friend' displays immaturity through a pay-out or put down, usually a completely random insult to achieve sadistic pleasure such as facebook 'likes'. only a real douche bag of a guy would randomly pay-out another. this cannot be titled to a true friend, as no true friend would do it. several things can happen before a douche moment; his mum could be selling herself, his girlfriend on pms, feeling unloved or sad with being a failure.

Alex: "hey i heard Daniel's being a real ass to Sam"
Joe: "yeah did you see what Daniel wrote on his wall?"
Alex: "yeah that was a real douche moment"
